Fax: +49 721 608-43758
The TTU Rheology and Formulation of Complex Fluids offers services for rheological characterization, processing, and stability of complex fluids. Complex, multi-phase fluids require careful product formulation and process design. We develop formulations of multi-phase fluids, whose processing and application properties meet the customers’ requirements.
Characterization of rheological characteristics in shear and strain is based on a broad spectrum of methods:
Mechanical methods (rotation and capillary geometry using a large range of measurement tools, piezo-high-frequency rheometry, ultrasound, CaBER) and
optical methods (multi-particle tracking (MPT) and diffusing wave spectroscopy (DWS)). Work can be carried out over a large range of shear rates and frequencies (10-3 – 106 s-1). Even local rheological differences can be identified.
In addition, various methods of particle measurement technology (dynamic light scattering, Fraunhofer scattering, single particle counting, image analysis) and structural characterization (fluorescence, light, and electron microscopy) are applied.
The TTU Rheology and Formulation of Complex Fluids has vast expertise and know-how relating to the characterization and formulation of the following substance classes:
Suspensions and dispersions

TTU Characterization of Polymers
Prof. Dr. Manfred Wilhelm
Telefon +49 721 608-43151
Fax +49 721 608-994004
The TTU Characterization of Polymers offers its customers a wide range of methods for the analysis of polymers. Comprehensive expertise and a number of characterization methods are available. Identification of polymers and analysis of viscoelastic properties in the melt or solid can be accomplished and may be complemented by imaging methods, if necessary. In addition, model polymers with a narrow distribution and customized topology can be synthesized by anionic polymerization. Thanks to this broad spectrum of methods, the TTU can offer analysis concepts tailored to various problems.
The following standard analysis methods are available: NMR and infrared spectroscopy for the identification of polymers, size exclusion chromatography (GPC or SEC) for the analysis of chain length and distribution, dynamic differential calorimetry (DSC) for thermal properties, and static and dynamic light scattering. A special method to analyze morphology is small-angle X-ray scattering (SAXS).
A major focus of the TTU lies on the mechanical properties of polymers in the melt and solid. Various shear and strain rheology methods can be applied to analyze melts. Solids can be analyzed by dynamic-mechanical thermal analysis (DMTA) or tensile-strain tests. Analysis covers all steps from specimen preparation to extrusion or injection molding to measurement to data analysis by experienced experts.
Moreover, the TTU is the only unit of its kind that develops new combinations of characterization methods to determine correlated properties. Work concentrates on measurement methods combining mechanical properties (rheology) with molecular properties (mobility by NMR and dielectric spectroscopy, order by SAXS) as well as on the combination of size determination (GPC) with chemical detection (IR or NMR). Combined rheo-NMR, for instance, enables analysis of mechanical properties in correlation with molecular stability, which allows conclusions to be drawn with respect to e.g. shear-induced crystallization in polymers. Combined GPC-IR allows for a correlation between size and chemical identity. The resulting data are essential for polymer blends and copolymers.
Professor Dr. Manfred Wilhelm studied chemistry at Mainz, Toronto, and Santa Barbara, his focus being on polymer sciences (in 1995, doctorate on solid-state NMR of polymers at the Max Planck Institute in Mainz). For two years, he worked as a postdoc at the Weizmann Institute, Israel. From 2004 – 2006, he was Professor for Mechanical Engineering at the University of Darmstadt. Since 2006, he has been heading the Polymeric Materials Group of the Institute for Chemical Technology and Polymer Chemistry of Karlsruhe Institute of Technology. He is Member of the Board and Spokesperson of the Research Training Group of the Collaborative Research Center SFB 1176 ”Molecular Structuring of Soft Matter.“ He pursued a number of cooperation projects with industry and is associate professor of Université Laval in Québec, Canada. Since 2008, Wilhelm has also been working in the Board Council of the Deutsche Kautschukgesellschaft (German Rubber Society). He was offered a professorship at the University of Bayreuth (2015) and the directorate (as successor of Professor G. Heinrich) of the Leibniz Institute of Polymer Research in Dresden, IPF (2016).
